What is a KC 18650 Li-ion battery with PCB?

It is a rechargeable lithium-ion battery in the standard 18650 form factor equipped with an integrated Protection Circuit Board (PCB). The PCB safeguards the battery cell against overcharging, over-discharging, and short-circuit conditions.

What is the advantage of using a battery with a PCB?

The PCB acts as a built-in safety management system. It continuously monitors the battery's voltage and current levels, cutting off the electrical pathway if thresholds are breached, preventing damage to the cell and your device.

What capacity options are available in this series?

The KC 18650 series offers a wide range of capacities to meet different application demands, including 2000mAh, 2200mAh, 2600mAh, 3000mAh, 3350mAh, and 3500mAh options.

Can these batteries be used in high-drain applications?

Yes. While standard capacities like 2000mAh are optimized for low-to-moderate drain applications, high-drain variants such as the 3500mAh model support a high continuous current output of up to 15A.

How should I store and maintain these 18650 batteries?

Store the batteries in a cool, dry place away from direct sunlight and extreme temperatures. It is recommended to keep them at approximately 40%–50% charge state during long-term storage and charge them periodically to maintain healthy cell life.
